I am afraid we cannot do that when we have an attorney representing us. Ask your attorney to contact the INS office regarding the receipts (we already paid him/her to do that for us, right?). As a standard practice, your attorney would tell you, as per INS instructions, we should wait for 90 days (in some case, 14 - 30 days) for an acknowledgment from INS, if we still don't hear within the specified time then only we can send a query to the INS office. Even then, all your attorney can do is sending a fax note to the INS office and wait for the reply. I know, you might be wondering what a crazy process, our ration card system back home is way better than this, Ahh!
. Anyway, the point is it is frustrating but these things take time.
Best of luck.
